Answer:
X and Y = 4
Well, it's a right triangle. The red box means 90 degree angle. So I would say that all the sides are equal.
Answer:
The inverse function is f(x) = (x + 7)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x -7
x = 2f(x) - 7
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) - 7
x + 7 = 2f(x)
(x + 7)/2 = f(x)
If I understand this, you have the equation 6(2x+7)-5. This is equal to 12x+37. Hope this helps.
